ANIMAL+RELEASING DEVICE.

Specification of Letters Patent. Patented N 12, 1918,.

Application filed July 12, 1917. SerialNo'. 180,118.

To all whom it may concern:

Be it known that I, CARL ARVID JOHNSON, a citizen of Sweden, residing at Chicago, in the county of Cook and State of Illinois, have invented certain new and useful Improvements in Animal-Releasing Devices, of which the following is a specification.

This invention relates to improvements in animal releasing devices and its object is to provide a device whereby a number of animals confined in stalls in a stable may be simultaneously released in case of necessity. A further object is to provide a device of this class that, in addition to releasing the animals, will operate to unlock the door of the stable and open the same. With the foregoing and other objects in view the invention consists in the combination and arrangement of parts to be hereinafter fully described, particularly pointed out in the claim and illustrated in the accompanying drawing which forms a part of this specification and in which- Figure l is a fragmentary view illustrating the door control mechanism.

Fig. 2 is a section taken on line 2-2 of Fig. 1.

Like reference characters sponding parts in both views.

The reference numeral 1 denotes the front of the stable, 2 one of the side walls and 3 the end wall. The stable door 1 is provided with the brackets 5 that extend above the top of the door and carry the rollers 6 that run upon the rail 7 secured to the said wall 1. The door, further, is provided with the arm that carries the apertured head 9 that slidably engages the cable 10 that extends along the face of the wall 1 and over the sheave 11, secured to the face of the wall 1, and carries the weight 12.

One end of the cable 10 carries the addenote correjustable collar 10 and terminates in a loop or eye 13 and said end is then bound to the main strand by the collar 14 and an eye-bolt 15 extending through an opening 16 in the wall 1 has its outer end removably inserted in the said cable eye 13, the inner end of said eye-bolt being connected by a chain 17 with a lever 18 fulcrumed in a bearing 19 carried by a piece of wall studding 20. A spring 21 also connects said lever and studding above the bearing 19 and a heel 22 formed upon the upper end of said lever and disposed substantially at right angles thereto normally has a bearing upon said studding to space the upper end of the lever therefrom. A cord 23 connected to-t-heupper end of the lever 18 passes over a sheave 24 carried by the studdingand carries a'bol-t 25 which normally connects the angle pieces 26, 27 carried, respectively, by the door 41 and studding 20 whereby said door is releasably locked in closed position from the inside.

A pull rope 28 connected to the lower end of the lever 18 passes over the guide sheaves 29, 30, through guide brackets 31 carried by the manger wall 32, over a guide sheav 33 also carried by said manger wall and is secured to a control lever 34 fulcrumed upon a block 35 carried by the wall studding 36. To open the door 1 under ordinary circumstances it is but necessary to enter the building from another door (not shown) and lift the bolt 25 and slide the door upon its rollers. To the pull rope 28, in each stall, I secure a pin 37 the free end of which is normally projected through the bifurcated end of a bracket 38 secured to the manger wall, said pin carrying a ring 39 that carries the hitching ring 410. One animal at a time is unhitched in the usual manner by disconnecting his halter strap from the ring 40. To release all of the animals simultaneously and open the door a the operator from inside the barn pulls upon the lever 34 thus pulling the rope 28 and moving the lower end of lever 18 toward the wall 1 and the upper end and heel 22 away from that wall against the tension of spring 21. This operation will also cause cord 23 to lift the bolt 25 and unlock the door and, through the medium of chain 17 withdraw the eyebolt 15 from the eye 13 of cable 10. The weight 12 at the end of cable 10 will, through the medium of collar 10 and arm 8, open the door; the pull rope will, at the same time, withdraw the pins 37 from the brackets 38 thus releasing the hitching rings and freeing the animals. The mechanism is easily re-set by again replacing the eyebolt in engagement with the cable eye 13, after the door 4 has been closed manually, and the pins 37 then reinserted in the brackets 38.

What is claimed is z--- In an animal releasing device comprising a stationary element and a sliding element, a lever fulcrumed to said stationary element and formed with a heel having a bearing upon said element, means for yieldingly retaining said lever in a normal predetermined Copies of this patent may be obtained for terminal loop, and a chain connecting said eye-bolt and the first named lever.

In testimony that I claim the foregoing as my own I have hereto aflixed my signa-t 15 ture in the presence of two subscribing Witnesses.

CARL ARVID JOHNSON.
